SAFETY LOOK FOR DRAi/VERS.

Application filed April 13, 1922. Serial lilo. 552,295.

a New York, have invented certain new and useful. Safety Looks for Drawers, of which the following is a specification.

This invention relates to locking devices as applied to tills, drawers, etc, and particularly to structures of the enclosed or trunk type.

One of the objects of the invention is to provide a. single, simple means for main taining a plurality of drawers arranged in a vertical row, 111 a closed position as against unwarranted entry, in an adequate and positive manner.

Another purpose is in the provision of means to prevent picking the lock by which the restraining bar is held, or otherwise manipulating the device to release the drawers.

A further aim is to produce a locking device comprised of few parts, essentially light in weight but possessed of requisite strength.

These objects are accomplished by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, forming an essential part of the disclosure, and in which Figure 1 is a perspective view showing a conventional type of wardrobe trunk in an open position and illustrating the application of the invention.

Figure 2 is an enlarged fragmentary front elevational view of the same, the lid being omitted.

Figure 3 is a perspective view of the bar engaging member and its associated parts.

Figure 4 is a fragmentary perspective view of the bar socket.

Figure 5 is a plan view of a bar engaging clip, or keeper.

The trunk body, generally designated by the numeral 10, is provided with a hinged lid or cover 11; and arranged transversely at spaced intervals in the body, are partitions 12 between which, and the top and bottom of the trunk, are drawers 13, 14, 15, and 16, respectively from the top down.

Fixed substantially central on the lower drawer front 16, is a metallic socket 17 open only at the top and secured by rivets or like fastenings at its extending flanged ends as shown.

Secured in the socket is about flat spring 18having upturned ends 19 curved inwardly to engage the lower end of a bar 20, which when positioned in the socket extends vertically past the upper partitions, over a portion of the top drawer 13.

A key-operated lock, generally indicated by the numeral 21 is permanently attached to bar at a point just above the top of the drawer 14, the lock having a spring actuated engaging bolt 22 at the right side within the lock casing, said casing having a side entry opening opposite the bolt.

A strap-like metal plate 23 is set into the underside of the upper partition, the same having ends 24 bent at right angles and set in the side frame of the structure, being firmly held by screws or equivalent fastenings.

At the center of the strip 23 is riveted an outstanding plate 25, containing a slot 26- partially separating the front keeper bar element 27, the same being of parallel width and raised above the surface of the plate by the offset shoulder or step 28, said keeper bar being suited to enter the side opening in the lock casing 21 and having a down-turned detent 29 engageable by the spring bolt 22. It will be noted that the shoulder or step 28 is of such size as to effectually block or close the side opening in the lock casing thus preventing the insertion of a knife blade or other tool for surreptitious withdrawal of the lock bolt.

A similar, but flat hook plate 80, fixed to the lower partition engages the bar 20 holding it closely against the edge of the partition and preventing it from springing under strain.

In operation, the bolt 22 being retracted by an entered key, the bar may be swung to one side, as shown in the broken lines in Figure 1, and thus raised out of the socket 17, releasing all of the several drawers simultaneously.

In securing the drawers the bar 20 is en tered into the socket resting against the spring elements 19 to prevent rattling, and turned in the manner of a lever so that the keeper bar 28 enters the lock opening and the detent 29 engages the spring bolt, holding the bar erect in front of the several drawers, positively preventing them from being drawn outward, such occurrence being further prevented by the clip shown in Figure 5.

Thus it will be seen that a simple device for accomplishing the purpose has been described in its preferred embodiment, but it will be apparent that minor changes, not involving the exercise of invention may be made within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A lock for drawers arranged in a vertical row and having fixed partitions therebetween, comprising a socket fixed on the front of the lowermost drawer, a spring having opposed curved ends secured in said socket, a plate carried by the uppermost of said partitions, a raised offset keeper bar 1ntegral with said plate, a detent on said keeper bar, a locking bar engageable between the ends of said spring in the socket, said locking bar extending past the edge of the uppermost drawer when erect, and a lock on said locking bar having a lateral open" ing to receive and conceal the keeper bar and within which the said detent is engaged by the lock bolt.

2. A multiple drawer securing means com-- prising a bar, a socket on the lowermost drawer receptive of the end of said bar, plates having open lateral slots extending outward from certain of the partitions between said drawers receptive of said bar, a detent carried by one of said plates, a lock on said bar having a casing completely concealing the lock bolt and mechanism, and a lateral opening in said casing to receive and conceal said detent, and within which said detent is engaged by the lock bolt.

3. A lock for drawers arranged in a vertical row and having fixed partitions therebetween comprisin a socket fixed on the front of the lowermost drawer, a spring having opposed curved ends secured in said socket, a metal strip fixed in the upper partition, a plate extending outwardly therefrom, a raised offset keeper bar integral with said plate, a detent at the end of said bar, a lock bar engageable between the elements of said spring, a spring lock carried by said bar, said lock having a lateral opening receptive of said offset keeper bar, means in said lock engageable with said detent, and a recessed keeper plate adjacent the lowermost drawer engageable with said lock bar when in erect operative position.

Signed at New iork, in the county of New York and State of New York, this 30th day of March, A. D. 1922.
